Set params command

Hi guysI am trying to make a time lapse camera using my old SX 210. I wrote a script to take pictures every 10 minutes, using the standard power saving tricks (screen off, turn to play mode between shots, etc). I will hack it soon to add an external battery.

Anyway, the camera will retract the lens after 1 minute in play mode, so my script has to constantly switch it to record then back to play mode. This wastes energy and actuates the shutter needlessly, and I was wondering if there is any way to change that 60 second value to something else (like 10K would be a good number). I found the param for my camera, it's 112, but so far I can't set it.

I was wondering, is there a technical reason for the lack of a set_parameter_data() function? Would it be hard to implement?

Well anyway, I found the magic location (the IsLensOut variable) for my camera.It's at IsLensOutAddr=0x31b8 for the SX210, in case someone googles it.It works just fine for my purpose, now the lens stays out without having to switch to/from record mode.
